Japan Utilities File for Atomic Plant Restarts With Regulator

July 8 (Bloomberg) -- Kansai Electric Power Co. and three other regional utilities applied to Japan’s nuclear regulator for safety checks, a step toward restarting reactors idled after the Fukushima atomic disaster in March 2011.

The applications filed today by Kansai Electric, Shikoku Electric Power Co., Hokkaido Electric Power Co. and Kyushu Electric Power Co. seek the Nuclear Regulation Authority’s clearance to operate 10 reactors with a total installed capacity of 8.84 gigawatts.

The applications cover 19 percent of the total capacity of Japan’s fleet of 50 functioning nuclear plants and represent enough power to supply 2.9 million Japanese households, according to calculations by Bloomberg.

All but two of Japan’s reactors are idled for safety assessments after the 2011 earthquake and tsunami caused meltdowns and radiation leaks at Tokyo Electric Power Co.’s Fukushima Dai-Ichi plant. The NRA was set up after the disaster to independently review Japan’s nuclear power.

Tokyo Electric, Japan’s biggest utility, hasn’t made a decision on when to turn in an application to restart reactors at its Kashiwazaki-Kariwa plant in Niigata prefecture, 220 kilometers (137 miles) northwest of Tokyo, Hiroshi Itagaki, a spokesman for the company better known as Tepco, said today by phone.

Tepco President Naomi Hirose said last week that the company would seek permission to start two reactors at the plant as soon as possible. The utility, which had a 685.3 billion yen ($6.8 billion) loss last fiscal year, said in May 2012 that it would return to profit this year if reactors at the plant are restarted.

Safety Checks

Kansai Electric, the nation’s second-biggest regional utility, filed to restart the No. 3 and No. 4 units at its Takahama facility, according to a statement on its website. The company will also seek the regulators’ endorsement for the No. 3 and No. 4 units at its Ohi plant, which had been given government approval to operate before the NRA was formed.

Hokkaido Electric filed for unit Nos. 1-3 at its Tomari plant, according to spokesman Hisatoshi Kibayashi. Shikoku Electric filed for the No. 3 unit at its Ikata plant, the company said on its website. Kyushu Electric filed for unit Nos. 1 and 2 at its Sendai plant and will file for unit Nos. 3 and 4 at its Genkai plant on July 12, spokeswoman Naoko Iguchi said.

The following table includes data on reactor types, original reactor start dates, current state of operations and status of safety-check applications to the NRA. Boiling water reactors (BWR), including advanced boiling water reactors (ABWR), must install filtration vents before restarting. Pressurized water reactors (PWR) are required to install the vents within five years after resuming operations.
